I have a Payne HVAC PH10JA042-C It's a 10seer 3.5ton, It had a number of leaks That I fixed, After fixing I pulled a vacuum It haled the vacuum for over and hour. Charged it. It seemed to be working But after a short time it stopped. The gauges low and high equaled out with the low side slightly higher. Could this be to low of a charge?
